Albert Barnes Commentary Matthew 27:8

"Wherefore that field was called, the field of blood, unto this day." — Matthew 27:8 (ASV)

The field of blood. The field purchased by the price of blood. The name by which this field was called was Aceldama (Acts 1:19). It was just outside the walls of Jerusalem, on the south of Mount Zion. It is now used as a burying-place by the Armenian Christians in Jerusalem, who have a magnificent convent on Mount Zion. Miss. Herald, 1824, p. 66. See the map of Jerusalem, and Matthew 2:1.

Unto this day. That is, to the day when Matthew wrote this gospel, about thirty years after the field was purchased.
